Description

  TECHNICAL FIELD The present invention relates to an automatic opening umbrella, and in particular, it is not only easy to assemble at the time of manufacture, but also an automatic that can easily separate and dispose of a metallic member and a non-metallic member when discarding a broken umbrella. It is about an open umbrella.

  In recent years, a large number of automatic opening umbrellas (also called jump umbrellas) have been sold for convenience of use. The structure of a typical automatic opening umbrella is the same as that of a hand-opening umbrella: an upper arm fixed to the end of a support and a lower arm that is slidably fitted to the support and opens and closes the umbrella by its sliding movement. In addition to the above, it has a medium crosspiece that is slidably fitted to the column between the upper crosspiece and the lower crosspiece. The base of the thin and short support bone pivotally attached to the middle part of the receiving bone is pivotally supported by the center and the bottom part. A powerful coil spring is fitted between the middle and lower crosspieces, and a clasp that can be raised and lowered in a manner of being biased in a direction protruding from the outer peripheral surface of the support is provided at a position near the support of the support. A push button is provided between the clasp and the hand for immersing the clasp in the column.

When the umbrella is squeezed by pulling it toward the hand with the hand on the hand, the coil spring is compressed by bringing the handpiece and the ribs closer to the handpiece, and the coil spring is compressed. umbrella becomes locked and closed in a position close to the hand by clasp the lower runner.

  When the push button is pressed in this closed state, the bottom roller released from the locking by the clasp is vigorously slid on the support column toward the top member with the middle roller by the resilient force of the coil spring, and the umbrella is opened.

  By the way, a normal umbrella is a non-metal made of a metal member (a support column, a main bone, a receiving bone, a supporting bone, etc.) and a synthetic resin (hereinafter simply referred to as “resin”) regardless of whether it is a hand-opening type or an automatic opening type. Although it is comprised from the manufacturing members (a hand, an upper wheel, a lower wheel, a middle wheel, a stone hammer, etc.), each member is connected permanently or in the state where decomposition | disassembly is very difficult. That is, the resin upper crossbone is fixed to the metal support by the nail, and the resin upper crossbone and the metal main bone are connected, and the resin lower crosspiece or the middle crosspiece and the metal support bone or the supporting bone are provided. Is connected by winding a wire (holding needle) sequentially inserted through a hole formed at the base of the umbrella bone around the outer circumferential groove of the wheel and twisting the tip of the wire.

  Therefore, the conventional umbrella not only takes time to assemble during production, but also separates the metallic member from the non-metallic member, even if the sheet can be removed relatively easily when the broken umbrella is discarded. This makes it difficult to recycle valuable resources. In recent years, especially when environmental pollution issues have been highlighted, the number of local governments that require the separate disposal of umbrellas has increased, and it has become an issue to facilitate this separate disposal.

Therefore, the present applicant has previously proposed a hand-open umbrella that can be easily assembled and can easily separate a metal member and a non-metal member such as a resin at the time of disposal (Patent Document 1). ).
JP 2001-275727 A

  By the way, in a hand-open umbrella, the resin skull and hand fixed to the metal support can be easily removed from the support, and the base of the metal main bone and the receiving bone can be removed from the resin top and bottom. As long as it is configured so that it can be easily removed from the potter's wheel, it is easy to separate and dispose of metallic and non-metallic parts. Since a powerful coil spring is shrunk between the two, if this coil spring cannot be disassembled with its elastic force completely de-energized, it will not only be difficult to disassemble, but also be dangerous. It is accompanied.

  Further, in the case of the automatic opening umbrella, when the umbrella is closed, the spring biasing force of the coil spring that is compressed between the bottom and the middle of the hook locked to the column by the clasp is medium Is transmitted to the parent bone via the receiving bone, and a force in the opening direction always acts on the parent bone. Therefore, when disassembling at the time of disposal, in the event that the umbrella is released from the engagement state with the umbrella closed, the top of the top is abruptly pulled to the near side by the resilient force of the coil spring. Because there is a risk that the umbrella will suddenly open and may be dangerous, you must take preventive measures.

  In view of the above-described circumstances, an object of the present invention is to effectively solve the problems peculiar to an automatic opening umbrella associated with disassembly for separation and disposal. In the following description, the upper part or the upper part means the side of the umbrella and the lower part or the lower part means the hand side of the umbrella.

  The spring accommodating cylinder of the lower wheel may be screwed from below into the inner periphery of the annular body provided with the support bone pivot part, or may be provided above the inner periphery of the annular body provided with the support bone pivot part. It may be inserted through. Furthermore, the spring accommodating cylinder of the lower wheel may be formed integrally with the support bone pivot support portion.

The second invention of the present application is an invention relating to the pivotal support structure of the receiving bone in the middle wheel in the automatic opening umbrella having the above-described configuration,
The above-mentioned medium wheel is provided with a plurality of receiving bone receiving grooves radially on the peripheral edge thereof, and a non-metallic annular body constituting the receiving bone pivot supporting portion, and is screwed onto the inner periphery of the annular body so as to be slidably fitted to the support column. A worn non-metallic support cylinder,
The support cylinder includes a lower cylindrical body on which the coil spring is wound on an outer peripheral surface, a flange that is provided at an upper end of the lower cylindrical body and receives an upper end of the coil spring, and an upper cylindrical body that extends upward from the flange. And coaxially and integrally,
The upper cylindrical body of the support cylinder is screwed to the annular body in such a manner that the upper surface of the flange is in contact with the lower surface of the annular body.

  In this case, projecting shafts that serve as pivots are formed on both sides of the base portion of the metal receiving bone, and the projecting shaft pivot groove that is substantially orthogonal to the receiving bone receiving groove is received by the annular body that constitutes the receiving bone pivot supporting portion. The upper cylindrical body of the support cylinder is screwed onto the annular body after the root part of the receiving bone is accommodated in the receiving bone container. It is preferable that the receiving bone receiving groove and the projecting shaft pivot supporting groove are configured to be covered with the flange by wearing.

  It is preferable that the upper cylindrical body protrudes upward by a predetermined distance in the axial direction from the upper end of the annular body in a state of being screwed to the annular body.

The third invention of the present application is an invention relating to a fixing structure of the upper wheel to the support in the automatic opening umbrella having the above-described structure and a pivotal support structure of the main bone in the upper wheel,
The metal strut is provided with a scissor positioning hole, and the non-metallic top scissors can be engaged with the flange-like main pivot support portion having a plurality of master bone receiving grooves radially around the periphery and the scissor positioning hole. An engagement portion for a column, which is cylindrical and is provided with an engagement protrusion on the inner peripheral surface and is coaxially connected to the parent bone pivot portion;
The upper crosspiece fitted to the post in a manner in which the engagement protrusion is engaged with the upper crosspiece positioning hole of the post is attached to the outer peripheral surface of the engaging portion by the upper crosspiece fixing member that is removably crowned from above. It is fixed to a support | pillar.

  It is preferable that the upper crossbone fixing member is screwed to the outer peripheral surface of the engaging portion, and it is more preferable that the upper crossbone fixing member is made of a stone bump.

  In addition, the engaging portion of the upper handle is composed of a pair of semi-cylindrical bodies connected to each other via a hinge portion having a hinge line extending in a direction parallel to the axis of the column, and the pair of semi-cylindrical bodies are the hinges. It is preferably bent along the line and formed into a cylindrical shape.

  In that case, it is preferable that one of the pair of semi-cylindrical bodies is integrally fixed to the main bone pivot support portion, and the engagement protrusion is formed on the inner peripheral surface of the other semi-cylindrical body. .

  Further, projecting shafts serving as pivots are formed on both sides of the base portion of the metal master bone, and a projecting shaft support groove substantially orthogonal to the master bone housing groove is formed on the upper surface of the master bone pivot portion together with the master bone housing groove. After the base part of the main bone is received in the main bone storage groove, the main bone storage groove and the projecting shaft are pivotally supported by screwing the stone butt through the collar member and the sheet after the base part is received in the main bone storage groove. It is preferable that the groove is configured to be covered with the collar member.

  Furthermore, it is preferable that the pole support member protruding from the outer peripheral surface of the support pillar is detachably attached to the support pillar at a position close to the lower face of the support pole fixed to the support pillar.

  According to the first invention of the present application, the support formed in a hook shape on the pivot ring fitted to the lower surface of the support bone pivot part so as to face all the support bone receiving grooves of the support bone pivot part of the lower arm. By simply hooking the base of the bone, the base of the support bone can be pivotally supported by the lower ring. In an automatic umbrella, the urging force of the coil spring that is retracted between the lower and middle skulls acts so that the supporting bone is always pulled to the tip side through the middle and the receiving bones. Therefore, even with such a simple pivot structure in which the root portion of the support bone is simply hooked on the pivot ring, there is no possibility that the root portion of the support bone is detached from the pivot ring. Therefore, if the urging force of the coil spring is not acting on the support bone, it is very easy to attach and remove the root portion of the support bone from the bottom ring, and the support ring can be removed from the support bone support portion. Combined with this, it is easy to separate and discard the metal member and the non-metal member.

  According to the second invention of the present application, the medium crosspiece is provided with a flange for receiving the upper end of the coil spring on the support column, which is provided with a plurality of receiving bone receiving grooves radially on the periphery and constituting the receiving bone pivot support portion. Since the support cylinder fitted slidably is screwed, the annular body and the support cylinder can be separated by rotating the support cylinder in a direction in which the support cylinder is unscrewed during disassembly. Therefore, in this separated state, if the root portion of the receiving bone is removed from the annular body constituting the receiving bone pivot supporting portion, the root portion of the receiving bone from the medium crosspiece can be easily removed.

  Then, projecting shafts serving as pivots are formed on both sides of the root portion of the receiving bone, and the projecting shaft pivoting groove substantially orthogonal to the receiving bone receiving groove is received on the annular body constituting the receiving bone supporting groove together with the bone receiving groove. The receiving bone receiving groove is formed by opening the bottom surface of the annular body, receiving the root portion of the receiving bone in the bone housing, and then screwing the upper cylindrical body of the support tube to the annular body. Further, by constructing the protruding shaft support groove so as to be covered with the flange of the support cylinder, there is an advantage that it is very easy to attach and detach the receiving bone to the medium skull.

  Further, the upper cylindrical body of the support cylinder is screwed onto the annular body and protrudes upward by a predetermined distance in the axial direction from the upper end of the annular body, so that the support cylinder is rotated by picking up the protruding portion. Thus, the support cylinder can be easily removed from the annular body.

  According to the third invention of the present application, the upper handle has a cylindrical engaging portion with respect to the support column that has an engagement protrusion on the inner peripheral surface that can be engaged with the support rod positioning hole of the support column. The upper crosspiece fitted in the post in a manner that the protrusion is inserted into the upper crosspiece positioning hole of the post is fixed to the post by the upper crosspiece fixing member that is removably crowned on the outer peripheral surface of the engaging portion. Therefore, it is easy to attach and detach the crossbones to and from the struts, and in particular, the engaging portions of the crosspieces are connected via hinge portions having hinge lines extending in a direction parallel to the axis of the struts. A pair of semi-cylindrical bodies connected to each other, and the pair of semi-cylindrical bodies are bent along the hinge line to form a cylindrical shape. If it is screwed to the outer peripheral surface of the joint The attachment of the upper runner, removal becomes extremely easy for the posts.

  In particular, as in the case of the receiving bone, projecting shafts serving as pivots are formed on both sides of the root of the parent bone, and the projecting pivot pivot grooves that are substantially perpendicular to the parent bone housing grooves are formed in the parent bone pivot portions together with the parent bone housing grooves. After the base part of the master bone is received in the master bone receiving groove, the master bone receiving groove and the projecting shaft are formed by screwing the stone member through the collar member and the sheet to the engaging part. By constructing the pivot groove so that it is covered with the collar member, by fixing the upper end of the upper bone to the support pole and the pivot of the base part of the main bone to the upper pole by attaching the stone thruster to the upper pole at the same time. Further, there is an advantage that the removal of the base of the main bone from the upper cross and the removal of the upper cross from the support can be simultaneously performed by removing the stone thrust from the upper cross.

  In addition, a removable upper wheel locking member that protrudes from the outer peripheral surface of the column is attached at a position close to the lower surface of the upper frame fixed to the column so that the umbrella closes when disassembling at the time of disposal. Even when the state of engagement of the crossbones with respect to the support is released in a state where the umbrella is in the open state, it is possible to prevent the umbrella from being suddenly opened in a manner in which the crosspieces are suddenly drawn toward the hand side. And after releasing the engagement state between the upper and lower poles with the umbrella open, and after removing the main bone from the upper and lower poles, it will not become an obstacle when removing the middle and lower poles from the upper and lower poles. Then, it is only necessary to remove the scoop wheel locking member from the column.

By removing the butt 22 from the top, it is possible to simultaneously remove the base portion of the main bone 4 from the upper crossbone 3 and remove the upper crosspiece 3 from the support column 2, so that the assembling operation of the umbrella and the metal member There is an advantage that the separation and disposal work between the resin member and the resin member becomes extremely easy.

  By the way, as described above, when the umbrella 1 is closed, the automatic opening umbrella 1 is compressed between the bottom and the bottom crosspieces 10 and 6 that are locked to the support column 2 by the clasp 18. The urging force of the coil spring 14 is transmitted from the medium crossbone 6 to the parent bone 4 through the receiving bone 8, and a force in the opening direction always acts on the parent bone 4. Therefore, when disassembling at the time of disposal, if the engagement state of the scissors 3 with respect to the support column 2 is released with the umbrella 1 closed, the scissors 3 will suddenly become close at hand due to the elastic force of the coil spring 14. There is a risk that the umbrella 1 will suddenly open in a manner of being pulled to the side, causing danger.

  Therefore, as is apparent from FIG. 17, a detachable upper wheel locking pin 27 protrudes from the surface of the column 2 at a position close to the lower surface of the upper frame 3 fixed to the column 2. Preventing unexpected occurrences. Then, after releasing the engagement state between the upper skull 3 and the column 2 while the umbrella is open, and removing the main bone 4 from the upper frame 3, the middle and lower skulls 6 and 10 are removed from the column 2. It is only necessary to remove the scissors locking pin 27 from the column 2 so as not to obstruct the time.
